We describe the use of tetrabutylammonium fluoride as a basic trigger for reactions capable of generating structurally diverse products from methyl propiolate and carbonyl derivatives. The processes are based on either chemodifferentiating multicomponent ABB' three-component reactions or bimolecular domino reactions, and they operate through three different and well-defined autocatalytic cycles. These
我们描述了使用四丁基氟化铵作为能够从丙炔酸甲酯和羰基衍生物生成结构多样的产物的反应的基本触发器。这些过程基于化学分化多组分 ABB 的三组分反应或双分子多米诺骨牌反应,它们通过三个不同且明确定义的自催化循环进行操作。这些催化循环有一个共同的特性:它们通过氟离子的酸碱反应产生催化量的乙炔盐或烯醇盐,但它们通过这些盐的自催化生成得以维持。
